WARNINGS
The controller has voltage present on the control cable wires, even when the power button
has been pushed to “Off”. Unplug the power supply and disconnect the 25-pin D-sub con-
nector before making any connections or cutting or splicing the cable wires. If the controller
has power and the control cable wires short out, this will damage the driver chips inside the
controller.
We HIGHLY recommend that you ground the chassis of the controller to your station ground.
When operating with over 200 watts, it is important that you do not transmit while the anten-
na is adjusting.
CONNECTING CONTROLLER
Once you have connected the power cord to the controller and plugged the other end of the cord
into the power outlet (the universal power supply can accept 100 - 240 volts AC, 50-60Hz), turn on
the controller and then check that the screen display shows “Manual Mode, Elements Home”. If it
does not display that then go to page 16 and retract elements. Then disconnect the power plug and
then plug the 25 pin control cable connector to the mating connector on the back of the controller.
Plug in the power plug to the controller then turn on the controller. It is then advisable to perform a
“Calibrate” function before using the antenna for the first time. This ensures the controller is in sync
with the antenna.
If the control cable connector comes loose at any time while the antenna is moving the calibrate
function will need to be done.
Also, on the back of the controller, there are two ports - “Data In” and “Data Out”. If you have pur-
chased the transceiver interface option, there will be two 9 pin d-sub male connectors in the ports.
If you have not purchased the interface, there will be a plastic cover over the ports. For more infor-
mation on the transceiver interface refer to the “Transceiver Interface” section.
Other options that are available with the SDA 100 controller are the Tuning Relay, Remote Driver
Board and Advanced Lightning Protection (ALP). These options will have different wiring configura-
tions on the back of the controller. Refer to each options section for more information.
